Google returns regular wordpress registration not custom

[Uncle Geo]

I'm, just setting things up for the first time and testing. I've made a registration page with custom fields and a signup page with all the Google Checkout buttons. As I understand it, S2Member sends users to Google to cough up the cash and when they've paid it drops them back off at the site onto my nifty new custom registration page (http://www.smallbusinessmn.org/wp-login ... n=register) with all my custom fields

-except it doesn't -it drops them to the standard wordpress login (http://www.smallbusinessmn.org/wp-login.php).

Oh, maybe it is, another test user says it worked so I was probably logged in or something. Never mind.

That's a good idea. What s2Member does, is creates a temporary Cookie after checkout, and passes it to the PDT page, which allows access to the level and CCaps that the cookie specifies to be passed to the registration page. Therefore, what probably happened is that it redirected you to /wp-login.php?action='register', and it picked up that you were logged in, and sent you to the login page instead.

So in short, you're right.
